title: Activation of the alternative complement pathway by blood culture isolates of Bacteroides fragilis.
abstract: Blood culture isolates of Bacteroides caused depletion of alternative complement pathway hemolytic activity, but no fall in C4 titers, when incubated in vitro with normal serum or serum containing 0.002 M MgCl(2) and 0.008 M ethylene glycol-bis(beta-aminoethyl ether)-N,N-tetraacetic acid.
